ATTACHMENT FOR VACUUM CARPET-CLEANERS.

Specification of Letters Patent.

Application filed J'anuary 17, 1912. Serial No. 671,547.

county of Dane and State of Wisconsin,

have invented certain new and useful Improvements in Attachments for Vacuum CarpetCleaners, of which the following is a specification. y

This invention relates to carpet cleaners and particularly to vacuum cleaners and more particularly to the connection between tge vacuum creating mechanism and the s 0e.

An object of this invention is to produce a joint adapted to be interposed between a pump or other like vacuum creating mechanism and the shoe of the cleaner whereby the vacuum creating medium, to be hereinafter termed a pump, may be moved within predetermined degrees with relation to the shoe thus insuring the proper positioning of the shoe with relation to the surface being operated upon even thoughthe pump is oscillated slightly.

A still further object of this invention is to provide a joint of the character noted which may be readily detached for the purpose of removing deposits therein or from tljie space between the operating parts there- 0 With the foregoing and other objects in View, the invention consists in the details of construction and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to the accompanying drawings forming part of this specification wherein like characters denote corresponding parts in the several views, and in which- Figure 1 illustrates an end View in elevation of the joint and its connections embodying the invention; Fig. 2 illustrates a vertical sectional view thereof; Fig. 3 illustrates a front View in elevation; Fig. 4 illustrates a vertical section of the two cylinders.

In these drawings 5 denotes an outer cylinder having open ends, the said outer cylinder having a nipple 6 extending from the wall thereof, which nipple is preferably internally threaded as shown at 7 for the purpose of receiving a nipple such as 8 of a shoe 9, it being understood that the shoe 9 and its means of attachment with the cylinder may be of any approved construction and I, therefore, do not wish to be limited with respect to these elements.

stationed Within the cylinder 5 and rotatably associated therewith is a cylinder 10 preferably having an integral head 11, at one end and a removable head 12 at the opposite end, said head having a flange 12 .of a diameter equal to the internal diameter of the outer cylinder 5, the said removable head being for the purpose of permitting access to the interior of the cylinder for the purpose of removing any deposits ofdust or the like which may accumulate therein. The cylinder 10. is provided with a circumferential slot 13 which is adapted to communicate with the nipple 6 on the outer cylinder 5, the provision of the slot insuring communication of the interior cylinder with the nipple of the exterior cylinder even though the interior cylinder partially rotates with relation to the exterior cylinder. The exterior cylinder 5 is provided with a slot 14 which permits the nipple 15 which is threaded in an aperture 16 in the inner cylinder to oscillate within predetermined bounds and by, reason of the joint produced the pump which may be connected to the coupling 15, may be moved with relation to 'the shoe 9 without displacing the shoe from its operative position.

It is preferable that a relatively tight joint be produced between the cylinders 5 and 10 although there must be sufficient clearance to permit movement of one cylinder with relation to the other. It has been found in practice that dust will, to a greater or less extent, collect between the two cyla inders and it is desirable, therefore, to dismantle the parts of the joint for the purpose of removing the deposit from between the cylinders, and, therefore, the parts have been simplified to permit the ready dismantling of the said parts. To accomplish said result, the coupling 15 may be removed from the inner cylinder and the said inner cylinder is then free to move longitudinally of the outer cylinder, thus, but one element is detached for dismantling the parts and is applied when the parts are to be reassembled, and it is in this simplified construction that the advantages in part are embraced.

I claim- In an attachment for vacuum cleaners,

an outer cylinder open at both ends, said Patented Feb. 11,1913;

' ed within the first mentioned cylinder,

cylinder having an opening extending partly around its periphery, and an internally threaded nipple opposlte said opening, said nipple adapted-to receive the threaded portion of a cleaning shoe, a second cylinder, said second cylinder being rotatably mountand having an integral end wall and having its end opposite the integral wall open, a removable cover in the open end, having a flange of a diameter equal to the internal diameter of the outer cylinder, abutting against the end of the second mentioned cylinder, the said. second cylinder also having an opening extending partly there around, and an internally threaded nipple opposite the said opening, a suction nipple having its end in the last mentioned internally threaded nipple, the said suction nipple being operative to retain the first and second mentioned cylinders in assembled relation to each other.

In testimony whereof, I hereunto affix my signature in the presence of two witnesses.
